Since the AuctionService comfortably sits in its Docker Swarm it’s time to actually use it with a first version of the IRATA Android App. Which would also bring me a step closer to becoming a Full Stack Developer (at least a little one

For building the app I opted to use Android Studio . It is based on Intellij IDEA . Since I am more of a eclispse user I was curious on how easy or complicated the switch would be.

Now that I finally got the ELK stack running and collecting the logs from my two “Auction-Service”-instances, it is time to check whether Docker swarms load balancer really does distribute the requests.

Now that vision and technology has been defined I start with setting up an environment for my project.

Setup the nodes for the cluster

Docker swarm needs at least three nodes (one master and two workers) in order to run.
These could be virtual machines or physical machines. You could even use Docker in Docker DinD to create the nodes of the swarm cluster.
There is a great post on how to do that here.

It’s been a while since I started working on actual application design and delivery in a cloud environment. Since a lot has changed since my first tries and experiences, I decided to continue this project incorporating my new insights and ideas.

The second hurdle on the roadmap to the Certified Cloud Architect is the “Cloud Technology Concepts” module and corresponding exam. The emphasis in this module is on looking at cloud technologies that enable some of the cloud characteristics already covered in the first module. Continue reading Cloud Technology Concepts
